This server has severe gaps in definition quality. Both tools lack proper descriptions (hello has a generic tool-level comment, get_weather has no description at all). Input schemas are minimal with only type information and no meaningful parameter descriptions. Output schemas are completely undocumented. The tool names are somewhat reasonable but lack the verb-noun clarity expected in production tools. Error handling is absent. This is a bare-minimum proof-of-concept implementation, not production-ready.

• Add full descriptions to both tools explaining purpose, return value, and example use. Aim for 50-200 characters each per production baselines.
• Replace placeholder parameter descriptions with actionable constraints. E.g., 'name (string, required): The person's name to greet. 1-100 characters, no special characters except hyphens.'
• Document return types explicitly. E.g., '@return: A string greeting message, e.g. "Hello, Alice" or "Howdy, Bob".'
• Add input validation and error handling. Return structured error responses like '{"error": "Invalid name: must be 1-100 characters", "suggestion": "Try again with a shorter name."}'
• Consider renaming 'hello' to 'send_greeting' or 'generate_greeting' to follow verb-noun convention.
• Add per-request error context. If the weather service fails, return '{"error": "Weather service unavailable", "retryable": true, "guidance": "This error is temporary. You can retry in a few seconds."}'
• Consider adding an enum or constraint for the 'city' parameter if there is a known list of supported cities.
